我有一个发布了NSDictionary的NSNotification:
NSDictionary* dict = [NSDictionary dictionaryWithObjectsAndKeys:
anItemID, @"ItemID",
[NSString stringWithFormat:@"%i",q], @"Quantity",
[NSString stringWithFormat:@"%@",[NSDate date]], @"BackOrderDate",
[NSString stringWithFormat:@"%@", [NSDate date]],@"ModifiedOn",
nil];
[[NSNotificationCenter defaultCenter] postNotification:[NSNotification notificationWithName:@"InventoryUpdate" object:dict]];
我如何订阅此书并从此NSDictionary获得信息?
在我的viewDidLoad中,我有:
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(recieveInventoryUpdate:) name:@"InventoryUpdate" object:nil];
和该类中的方法:
- (void)recieveInventoryUpdate:(NSNotification *)notification {
NSLog(@"%@ updated", [notification userInfo]);
}
当然,它会记录一个空值。
最佳答案
这是[notification object]
您也可以使用notificationWithName:object:userInfo:
方法发送userinfo
